Principle of coffee machines of different types


Even those people who love to drink coffee do not always know that there are several types of coffee makers. Meanwhile, the principle of the work of a geyser coffee machine differs somewhat from a drip or a pump, and, therefore, differs in taste and coffee, which they prepare.

French press

Let's start looking at coffee makers from the simplest type - a French press. The French press is a flask, inside of which a piston with a filter runs.

Pour the ground coffee on the bottom of the flask and fill it with hot water. When the coffee is brewed, lower the piston, which will press the coffee grounds. From above there will be a pure aromatic drink which can be poured into cups and to drink. This way of brewing is very similar to our popular tea presses.

Drip type

Drip type coffee machines are often found in apartments and small offices. In it, heated water brews coffee, passes through a filter and gradually drips down. In such coffeemakers, a cold water tank is provided on top and a container for the finished hot beverage is located at the bottom.

The main difference between the drop-type models in the power, the volume of the bulb and the material from which the device is made. You should also pay attention to the filter (paper, nylon, metal). In many models, the filter is replaceable.


Geyser type

Coffee makers of the geyser type work with accuracy on the contrary. In appearance they look a bit like a metal teapot, but inside they are divided into two parts. Water is poured into them in the lower part, and ground coffee is poured into the filter located above it. When the water boils, it rises up the tube, brews the coffee, and the finished drink is in the upper part.

Let's find out how to choose a geyser coffee machine, what should we pay attention to?

  • It can be powered by electricity or heated by gas.
  • Pay attention to the size, because at a time you can cook only a certain amount of coffee, no more and no less.
  • It is very convenient if the coffee maker has a water fill indicator.
  • The handle and the lid should be warmed least of all so that you are not burned.

Coffee makers of the geyser type are preparing a very fragrant, pleasant drink, and at a price they are not very expensive. They are very fond of in Italy, so sometimes coffee, brewed in them, is called Italian.


Carob type

The difference of the horn coffee maker is that the ground coffee is poured and compacted into a special cup-horn, which is fixed from below. When the water boils, the steam creates a certain pressure. At some point a barrier is opened and steam passes through the ground grain, brews them.


The taste of coffee depends on the pressure under which the steam passes and to what temperature it heats up. Of great importance is also the choice of grains, the degree of their grinding and your skills in the selection of varieties and ramming.

Espresso coffee machines

This is a fairly large group of coffee makers, which, by the way, includes the carob-type. Espresso coffee machines can be divided into several types, depending on the principle of operation. At all at them one general - coffee is made by a hot steam. Here are their main types:

  • steam;
  • piston;
  • pump;
  • air-pump.

In addition, coffee makers can be manual, automatic and semi-automatic. Let's describe, for example, how a pump coffee machine works. This is the most common type due to its relatively low price and the ability to cook a very fragrant and tasty drink.

The water is poured into a reservoir with a valve. When we turn on the appliance, some of the water is pumped to the boiler. There it heats up and turns into steam. Steam-water mixture under high pressure is fed to coffee and brews it. The finished drink drains into a cup. If the coffee maker is equipped with a cappuccinator, then a tube is withdrawn from the boiler, through which steam can separately escape.


In more modern machines, instead of a conventional boiler, a special thermal block is installed, which can heat the water to a predetermined temperature. This allows you to expand the capabilities of the device (prepare more portions and different types of drinks) and shorten the time of preparation of coffee.

Capsule Type

Recently, the popularity of capsule or chalped coffee machines has been increasing. In them, the person has the smallest role. He should just load a ready-made capsule with pressed coffee, check if there is water in the tank, and press the button.

The machine pierces the capsule, heats the water and gives it under very high pressure to the pressed coffee. The finished drink will pour from below into the cup or cup, and the used capsule will move into the container, from which they will go to the trash can at their hour.

Realizing that the tastes of people are different, some manufacturers make coffee machines of a mixed type, in which the loading of capsules is provided, and there is also the possibility of using ground beans of a variety chosen personally you. In terms of their design, such devices are quite complex and require careful handling.
